Kaching · grad lines

Does it graduate? Put ETH on it.

A grad line is one question with two sides: will this coin cross the graduation threshold before the deadline, yes or no. Stake a side while staking is open. After the deadline anyone can resolve the line from the coin’s own on-chain graduated flag — no mod, no oracle, no Kaching discretion — and the winning side splits the pot minus a 3% rake.

Unlike a price bet, this outcome can be bought. The board says so in plain language before it shows you a single number.

Staking is paused

New stakes are paused while these markets are redesigned — a security review found the outcome can be bought cheaply at settlement. Settling and claiming still work, so any position you already hold can be closed out normally.

This outcome is buyable. Treat it that way.

A YES staker can simply buy the coin themselves to force graduation, then sell into the pool they just seeded and recover most of the spend. Measured on a real curve: profitable by up to 178x near the line. The contract caps NO stakes, but that cap is checked only when each stake lands and is never re-checked afterwards — ordinary trading has been measured drifting it 37x past its stated bound, so treat it as no protection at all. Opening several lines on the same coin multiplies the payoff for one forcing spend. The YES/NO bar is the split of staked ETH, not a win probability. Kaching takes a 3% rake, holds no position, and cannot pick a winner. Demo only, on a demo chain: these markets have no real value, and they are not enabled on any chain where money is real. Not financial or gambling advice — check your local laws.

How a line settles

  1. 1 · staking
    Anyone can stake YES or NO until the staking clock closes. NO stakes are capped near the ETH it would take to force graduation, which bounds the size of a squeeze.
  2. 2 · running
    Staking is shut. The coin trades as normal and the line runs to its deadline.
  3. 3 · resolve
    After the deadline anyone can call resolve. The contract reads the coin’s graduated flag and locks the outcome. If either side has no stake, or the curve cannot be read, the line is VOID and everyone is refunded with no rake taken.
  4. 4 · claim
    Winners claim their share of the pot minus the 3% rake, pro rata to their stake. Every action is signed in your own wallet; Kaching never holds a key and never holds a position.
